RVResult

At each output time, the following results are stored:

Entity

Component Names

RV

RVAL, RVAL1

The following occurs automatically when the model.simulate() method is invoked with returnResults=True.

• At T=0, for each RV in the model:
  • An RVResult object is created.
  • The object is stored in the SimulationResults container object.
• At each output time (including T=0):
  • For each RV in the model:
    • The RVAL and RVAL1 results are appended to the RVResult object.
• Thus, at the end of the simulation, the SimulationResults object is fully “populated.”

Assume a model, M, is given to you.

• Perform a dynamic simulation from 0 to 2 seconds with 200 output steps.
• Extract the time history for the RVAL component of RV response1.
• Plot the RVAL1 time history in matplotlib.

# Perform a simulation
run = M.simulate(type=”DYNAMICS”, end=2, steps=200, returnResults=True)

# Get the RV data from the run object
rv = run.getObject (model.rv68)

# Extract the time and RVAL1 signals
times = req.getComponent (“times”)
RV1   = req.getComponent ("RVAL1")

# Plot the RVAL signal
import matplotlib.pyplot as plt
plt.plot   (times, FZ)
plt.title  (“RVAL1 vs. Time”)
plt.xlabel (“Time”)
plt.ylabel (“Power [KW]”)
plt.grid   (True)
plt.show   ()
